I'm a new member and have some questions about design.
I am an ultralight pilot and own a Bowers Fly Baby currently under restoration.
My inspiration in design is the Sisler Cygnet, Ison Airbike, Cvjetkovic Ca-61, Wittman W-8 and publications by Rhodes, Thurston, Bowers, and the early Sport Aviation archives.
The build plan is steel tube fuselage, wooden/fabric wings, wooden/fabric tail group, single seat. Dimensions are 28' wing span with19' length ( to accomodate my existing hangar).
Recently I found this design, the Oskbes MAI-223, and was wondering if people could give me some ideas regarding the basic design.
OSKBES MAI MAI223
I am interested in the benefits of eliminating the fuselage wing junction. What sort of gains might be expected from the Mai-223 wing?
The forward swept wing also interests me. I have done some research and find the concerns about divergent wing stresses well controlled in the planned flight envelope by the wooden geodesic system used in the Cygnet.
I place visibility very high on the mission list for the design. I trained on a conventional pilot forward and rear engined ultralight. It makes a helicopter seem confined. However a high rear mounted engine in a light weight UL design is not safe by my level of risk management.
It seems possible to use a front mount engine and pilot sitting just forward of the leading edge to see into turns in the circuit with forward sweep balance points. Any comments?
